http://BobGaronTraining.com If burpees weren't enough, and no actually they never are, I have a one burpee progression that I love. It's called a "Chirpee". Essentially a chirpee is a burpee combined with a chin up- thus the name chirpee. In this video Laurence shows us a great chirpee. If that wasn't enough I even through in a box jump between the burpee and chin up. I we can call it a "Box Chirpee".
